CONCRETE REPAIR IN THE FUTURE TURN OF THE CENTURY - ANY PROBLEMS?

It is noted that when details are correctly designed and specifications are properly prepared and complied with, the repair process will possess properties that will be serviceable and durable. The paper delineates some of the major issues to consider in achieving long-lasting concrete repairs. Comments are made on the current state of concrete repair. In order to produce durable repair with limited and predictable change over time and without deterioration, it is necessary to consider the factors affecting the design and selection of the repair system, as a whole system. The importance of this systems approach to repair is emphasized. Factors in such a systems approach to repair are noted and discussed: compatibility with existing material; dimensional compatibility; chemical and electrochemical compatibility; permeability compatibility; condition of the interfaces; properties of the environment; and workmanship.
